THE SHORT ANSWER
Write a drain-cleaning estimate by affected fixture, access point and included service attempt. Define what the customer receives if the line cannot be cleared under the stated scope.
Use this fictional two accessible sink drain lines in Manchester to plan the estimate. The agreed work is: Clear two slow-draining sink lines through accessible existing cleanout or fixture connections. Include setup, one defined service attempt per line, reassembly, flow check and clean-up. No pipe replacement, camera inspection or guarantee against future blockage. The matching sink drain cleaning example and PDF shows the same inputs. These quantities and rates are teaching examples; use your own site measurements, product selections, supplier information and labour figures for a customer job.
1. Identify the affected fixtures
List each sink, the reported symptom and the planned access point. A single whole-house drain line item hides which sections of piping the service actually covers.
2. State the included attempt
Describe the tool access and work limit at a service level without promising a result that inspection cannot support. If the line remains blocked, explain how diagnostic work would be approved.
3. Count reassembly work
Removing a trap or restoring an access opening takes time. Give that work a line when the connection needs to be taken apart and checked after service.
4. Set the handoff boundary
Include a visible flow check and clean-up. Make clear that an apparent improvement is not a guarantee against recurring obstruction or hidden pipe defects.
Calculate the measured lines
The PDF uses 6 separate items. For example, Trap removal and reassembly allowance is 2 each × £52.00 = £104.00; Flow check and documentation is 2 each × £32.00 = £64.00. Check that each unit describes the work being priced: area for a surface, metres for a run, and a count or defined lump sum for a discrete task. A material purchase allowance can differ from the installed quantity when product sizes, cuts or layout require it.
Adding the 6 rounded line amounts gives £648.00. The example PDF uses a 0% tax input and no markup; those settings do not determine how to price or treat an actual job. Do not copy the rates as a local price guide.
Check the scope before sending
- Name both affected fixtures.
- Confirm access points.
- Define the service attempt and next diagnostic step.
- List reassembly and clean-up.
Outside the base scope: No pipe replacement, camera inspection, excavation, main-line service or guarantee against recurring blockage.
Confirm the site address, selected products, access, quantities, customer details and validity date. If opening the work reveals a different condition, record the change and update the relevant line before asking the customer to approve the revised work. Preview every page of the PDF so the written scope, line amounts and total tell the same story.
Common questions
Should an unsuccessful cleaning attempt be billed?
State the agreed service scope and billing terms before work. If further diagnostics are needed, present a separate scope and price.
Is camera inspection part of drain cleaning?
Only if listed. This example prices two sink-line service attempts without camera work.
